The Qomroud Tunnel Project Lot number 7 (QTP7), which is the subject of this study, is part of the Dez-Qomroud water conveyance tunnel projects that will convey water from the adjacent Dez Highlands to a central Iran watershed known as Qomroud. Comprehensive engineering geology and rock mechanics studies have been conducted to determine geological-geomechanical characteristics of the geological strata along the QLT7 tunnel route. Results from these field and laboratory tests are presented and discussed in this article.
